Micro Switch Introduction
The HK-14 series offers highly flexible customization options to meet differentiated application requirements. Operating force can be customized (less than 5.0 N in the lever-free state, standard 30±15 gf), with an operating stroke range of 0.6–1.5 mm, suitable for different trigger force and displacement scenarios. Lever styles are customizable, including straight, bent, and roller levers, which can match various mechanical transmission structures. Contact forms cover the full range of SPDT (1NO 1NC), NO, and NC.
The product has obtained major global safety certifications including UL, C-UL, ENEC, VDE, CE, CB, TUV, CQC, and KC, complies with the IEC 61058 standard, and meets market access requirements in Europe, America, Asia-Pacific, and other regions. The company has been certified under the ISO9001 and IATF 16949 quality management systems and strictly implements the RoHS and REACH environmental directives, achieving refined control throughout the entire production process. Leveraging 6 national invention patents and 48 utility model patents, the HK-14 series reaches industry-leading levels of reliability and consistency.
